IMPROVEMENT IN SHUTTLES FQR WEAVING WIRE-CLOTH.

Specification forming part of Letters Patent N 0. 117,837, dated August8, 1871.

To all whom it may concern:

Be it known that we, CHARLES H. WATERS, of Groton, and \VILLIAM ORR,J11, of Clinton, both in the Commonwealth of Massachusetts, haveinvented a new and useful Improvement in Shuttles for \VeavingVVireCloth; and that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing, inwhich Figure 1 is a plan view of the shuttle, showing the bobbin anddeliveryrolls with our improve ment applied and Fig. 2 is a separateplan view of the revolving iriction-finger, to be hereafter described.

()ur invention relates to that class of shuttles which carries a bobbinhaving one head, and from which the wire is drawn off over the other endof the bobbin by the flight of the shuttle. In shuttles of thisdescription the wire necessarily receives a turn of twist every time anamount of wire equal to the circumference of the roll of wire on thebobbin is drawn off; and, owing to the rigidity and elasticity of thematerial of the wire, it tends to kink under the action of such twistand make imperfect cloth. A device has been heretofore invented and putin use for con" trolling this tendency to kink by putting friction onthe body of wire wound upon the bobbin, so as to keep the wire underrestraint sufficiently for that purpose while being delivered from thebobbin. Our invention consists in certain means for putting suchrestraint upon the single thread of wire which is being delivered fromthe bobbin and before it reaches the delivery-rolls.

In the accompanying drawing, a represents the frame of the shuttle, inwhich is mounted in the usual manner a bobbin, 1), having but one head,and over the opposite end of which the wire is drawn by the flight ofthe shuttle through the shed. \Ve attach to the front end of thespindle, suitably formed for that purpose, on which the loaded bobbin isplaced, a piece which we call a revolving friction-finger, c, and whichis so constructed and attached to the front end of the spindle that itmay revolve around the same, and which is made with an arm, (1,extending in such direction that its salient end shall lie near to theside of the bobbin in front of the mass of the wound wire. This salientend is formed with a loop or hole, 0, through which the thread of wire,as it is drawn off from the bobbin, passes on its way tothedelivery-rolls As the strand of wire is taken by the deliveryrolls in orabout the line of the axis of the bobbin it will be seen that the linewhich the wire passes through, leading from the bobbin to thedelivery-rolls through the said loop or hole a, is angular, and,consequently, the strain upon the wire, tending to bring it into astraight line, will keep it bearing hard against the edge of such loopor hole; and this pressure of the wire upon it causes the friction-armd, on which it is formed, to revolve around its axis, (which, as beforestated, coincides with the axis of the bobbin,) and thus keeps therunning thread of wire under a constant and practically uniformrestraint suf ficient to hold it from kinking, as before mentioned.

We have shown in the drawing a guide or funnel, h, set in front of thedelivery-rolls and in the line of the axis of the spindle, and throughwhich the running thread of wire may be guided directly to the rolls.This may be dispensed with, although in practice we find it the betterarrangement. We have also shown the rotating finger c as formed with twosimilar arms, one of which is lettered e,- the other arm is merely forthe purpose of balancing the arm 0, and can be dispensed with, and, ifused, its shape is immaterial.

WVhat we claim as our invention, and desire to secure by Letters Patent,is-

The revolving friction-finger, constructed and operating as described,in combination with the wire-carrying bobbin, for the purpose of holdingthe running thread of wire under restraint as it is drawn through thedelivery-rolls, substantially as described.
